perfSONAR User Q&A and Other Discussion

[Daniel Doyle <>]

Hi Tanno,

Correct, the endpoints are capable of performing tests but not storing or visualizing the results. What you are describing sounds like the textbook example for a central measurement archive setup. Check out some of the docs here: http://docs.perfsonar.net/multi_ma_install.html

In short, you can set up a number of these endpoint hosts that perform tests to other hosts, but have them ship their results off to a "big" host that is running the full UI, measurement archive, etc and then do all the graphing and such there.

You may actually want to start here: http://docs.perfsonar.net/multi_overview.html. One of the potential gotchas for people doing this is that ad hoc tests, such as those initiated by you off the command line, don't store their values back to any measurement archive. A lot of people address this by using the mesh configuration tools to have endpoints pull down their test instructions which get converted automatically to regularly occurring tests and, once things are configured correctly, will ship their results back to the central MA.

Hope that helps. As always, the lists are here if you get stuck or have questions.

Hi Dan,

Thank you for your reply, things are more clear now.

When there is no UI, then I cant view results in graphs? or whats the way to see tests graphs in my solution?

Im working on a reasonably priced active WiFi monitoring solution, that just does tests and results are actually seen from some other computer (or network).

In abstract first testing solution Im glad when I can do tests, see results on the same device and maybe somehow generate these graphs with some other tool?

Hi Tammo,

Thanks for the feedback. It looks like the documentation needs a minor fixup - the init script for the ls registration daemon on Debian is "/etc/init.d/perfsonar-lsregistrationdaemon". I will get that updated here in the docs shortly.

In regards to port 80 connectivity, for Debian in 3.5 there is no web UI like there is on CentOS. This is being worked on and support will be added in the future. The perfsonar tools and testpoint contain (roughly) the packages and command line tools needed to perform latency and throughput tests, such as bwctl and owping, along with a few perfsonar accessories icluding the ls registration.  If you look under "Step 2: Install the packages" in the link you reference you can see more details there. Sorry if there was any confusion.

Hello,

I used this guide: http://docs.perfsonar.net/install_debian 

I instaled packages: perfsonar-tools, perfsonar-testpoint

perfsonar-testpoint should install ls-registration daemon.

But when I try to start it up by running command: /etc/init.d/lsregistrationdaemon start
then i get to know that there is no such thing... (all other services are OK)

Then there is a file /etc/perfsonar/lsregistrationdaemon.conf 
When I opened this file, there wasnt lines like there is on this guide:

##Hostname or IP address others can use
to access your service
#external_address   myhost.mydomain.example

##Primary interface on host
#external_address_if_name eth0

So i just added lines, to get to the web interface and test if it works and tests:

external_address
localhost
external_address_if_name
lo


Then I
restarded my Raspberry, started all services (still get an error
on  /etc/init.d/lsregistrationdaemon start) 
and when trying to
access to web interface by going to http://127.0.0.1  it says no
access
and when looking what ports are listened with netstat there is
no port 80



Could you please help me? Because im out of
ideas.
Many thanks,
Tammo.
